MOLD FOR CASTING ANODES.

SPECIFICATION forming part of Letters Patent No. 631,471, dated August 22, 1899.

To all whom it may concern.-

Be it known that I, JOHN T. MORROW, residing at Great Falls, county of Cascade, State of Montana, have invented certain new and useful Improvements in Molds for Casting Anodes, of which the following is a description, referring to the accompanying drawings, which form a part of this specification.

In another application filed on'the 21st day of April, 1898, Serial No. 678,346, Ihave set forth an improved anode. The present invention provides a mold particularly intended for casting such form of anode and similar form.

The nature of the invention will best be understood from a description of the accompanying drawings, which show a preferred forms.

Figure 1 is a plan View of the mold; Fig. 2, a cross-section on the plane 2 2 of Fig. 1; Fig. 3, a detail view showing a portion of the mold and clip-holder in place; Fig. 4, a cross-section of Fig. 3 on the plane 4 4; Fig. 5, an edge elevation of one of the clip-holders; and Fig. 6 shows in cross-section, on a plane corresponding to 2 2 of Fig. l, the anode and-its retaining-clip.

Throu ghont the drawings like letters of reference indicate like or similar parts.

The anode B, Fig. 6, is of cast metal and provided with clips 0 of sheet metal, so formed that the ends D are cast into the anode and thereby secured. The mold E for casting the anode is shaped to the form required-such, forinstance, as shownin Fig. 1-having, preferably, 'two lug-forming portions F. The wall K of the mold is much lower at the points G than at the other points and forms a low dam, upon which the ends D of the clips O rest, as seen in section in Fig. 4. A holderblock H is then placed on each clip and is adapted to fit snugly about the ends D of the clip and form a continuation of the wall of the mold above the dam or bridge G, so as to confine the molten metal, while allowing the ends of the clips D to project into the molten metal and be thereby cast into the anode. I

prefer to arrange the holder-block and adja- Application filed May 25, 1898. Serial No. 681,678. (No model.)

cent parts in the way shown in the drawings that is to say, I provide projecting portions L on the mold E outside the low wall or dam G, and I fit the weights or holders for the clips to these projections or extensions L, so that when in place the downwardly-projecting lugs M lie on either side of the extensions and insure the proper placing of the clip-holders. The clip-holders are also provided with a downwardly-extending edge or dam O, which comes opposite and registers properly with the dam G, leaving room enough between for the ends D of the clips O.

In using such a mold and clip-holder the clips are first laid in position and the holders then placed upon them. The molten metal is then poured into the mold E and flows into the lug-forming recess F of the mold. It surrounds and embeds the ends D of the clips, but is held in check by the fixed dam G and removable clip-holders H. As soon as the metal has cooled it is taken from the mold, with the clips 0 secured to it, as shown in Fig. 6.

What I claim, and desire to secure by these Letters Patent, is as follows:

1. A mold having at one or more points a low dam or wall, an extension lying outside said low dam or wall and a clip-holding device H supplementing the said low dam or wall and fitted to the said extension to register accurately in position therewith, the said mold being entirely open and without top in the vicinity of the said clip-holding device, substantially as set forth.

2. The shallow open mold having one or more extensions separated by a low dam or wall from the mold proper, and a clip-holding device adapted to fit freely over and register with each said extension and supplement the said low dam or wall, substantially as set forth.

In testimony whereof I have hereunto set my hand this 2d day of May, 1898.

JOHN T. MORROW.
